-LRB- CNN -RRB- -- A body found in an Indiana lake has been identified as that of Teleka Patrick , the Michigan doctor who 's been missing since December , the Porter County Coroner 's Office confirmed .

Her body was discovered Sunday in Lake Charles , west of Gary , Indiana , officials said .

The cause and manner of death are still pending further investigation , but are consistent with drowning , the coroner said in a statement Tuesday . An autopsy revealed no trauma , the statement added .

Mysterious disappearance

The 30-year-old medical resident failed to show up for work on December 6 in Kalamazoo , Michigan . The night before , her 1997 Lexus was discovered abandoned more than 115 miles away in a ditch off of Interstate 94 in Indiana , directly south of the lake where she was ultimately found .

Police brought out dogs to track Patrick 's scent . They led investigators out of the ditch where Patrick 's car rested to the highway . There , the scent went cold .

`` We looked everywhere , '' Sgt. Rick Strong of the Indiana State Police told CNN in December .

Videos provide clues

Surveillance video and home videos uploaded to YouTube provided investigators with clues about Patrick 's movements in the weeks , days and hours before she vanished .

The YouTube videos showed Patrick talking , cooing and singing to someone unnamed and apparently unknown . Patrick 's mother told CNN she was n't aware of any romantic relationship her daughter may have had . But the videos have an intimate feel to them .

`` Hi , baby , '' Patrick says in one . `` I am just coming to you to say ` hi ' and tell you about my day . ''

In another video , Patrick shows a table set for two with omelets and pancakes .

`` If you were here , this is what would be your plate , '' she coos .

In a surveillance video from a Radisson hotel in Kalamazoo , not far from where she worked , Patrick is seen on the night of December 5 around 7:30 p.m. , hours before police found her car in Indiana .

She spent about 10 minutes talking with employees at the reception desk but ultimately left . There 's no audio on the video , and it 's not clear why Patrick failed to book a room .

But at 7:48 p.m. , she strode across the hotel 's tiled floors , out the door and onto a hotel shuttle bus .

Those are the last known images of her .

Her family says Patrick , who had just moved to Michigan , bought a plane ticket to come visit them for the holidays in Florida .

In January , family members urged investigators to remain focused on the possibility that foul play was involved in her disappearance , after reports surfaced that gospel singer Marvin Sapp had filed a personal protection order against Patrick in September .

In court documents , Sapp said Patrick `` has claimed him as her husband , had moved from California to Michigan , joined his church , had contacted his children and had been to his home .

`` I have at least 400 pages of correspondence from her which I have never responded , '' his complaint reads .

Questions remain

While the discovery of Patrick 's body answers some questions , it leaves many more unanswered for the grieving family of a young doctor described as `` wonderful , '' `` beautiful '' and `` talented . ''

Investigators have said they have no evidence of foul play , but they also do n't have conclusive evidence that Patrick 's movements on December 5 were voluntary .

`` We have scoured , searched and looked at everything we could possibly look at -- all the exits , all the businesses , all the hotels , '' Strong said late last year . `` We posted fliers ; we talked to neighbors -LRB- who live near the highway -RRB- . We did a full-blown , on-the-ground search in the wooded area north of where the car was . ''

Carl Clatterback , a private investigator hired by Patrick 's family , told CNN that investigators are looking into the videos . A central question : Who was Patrick talking to in the videos and does that person know anything about what happened to her ?

CNN 's Tiffany Campbell and Julia Lull contributed to this report .
